The emergence of "Internet of things" breaks previous traditional thinking, which integrates physical infrastructure and network infrastructure into unified infrastructure. There will be a lot of resources or information in IoT, so computing and processing of information is the core supporting of IoT. In this paper, the authors introduce "Service-oriented computing" to solve the problem where each device can offer its functionality as standard services. Here, they mainly discuss the access control issue of service-oriented computing in Internet of Things. This paper puts forward a model of Workflow-oriented Attributed Based Access Control (WABAC), and design an access control framework based on WABAC model. The model grants permissions to subjects according to subject attribute, resource attribute, environment attribute and current task, meeting access control request of SOC.
